Description of the Related Art Water supply and sewerage systems are generally operated for 24 hours by a water supply system that collects water from a water intake source from a river or the like, filters the water, and supplies purified water, or a sewerage system that treats organic substances and discharges the water to a river. Here, looking at the water supply facilities, the filtration ponds of the entire process use granular activated carbon to filter and purify impurities, sterilize chlorine, and send water.

低下する。Conventionally, granular activated carbon filtration ponds have a step of removing impurities by backwashing about every one week because impurities accumulate in the water and cause clogging.
Even if the backwash cycle is repeated, the removal rate of impurities decreases in one to two years.

４ｄは回転軸の冷却保持用である。FIG. 8 shows an example in which the heating / regenerating apparatus 20 uses city gas. The used coal hopper 23a is mixed with the dilution water 23b, pumped by the slurry transfer pump 23c, drained substantially by the screw dehydrator 23d, and put into the upper part of the regeneration heating furnace 24. At the center rotating link 24c on the side of the multi-stage furnace,
It is raked by the rotating arms of each stage and sequentially moved to the lower stage, heated by the fuel valve 24b using the city gas 24a,
From the upper stage, it is activated by steam 24e in the order of drying ⇒ carbonization ⇒ activation, dropped on quench tank 24f, and stored in regenerated coal tank 24h by slurry transfer pump 24g.
The exhaust gas from the furnace is reheated in the secondary combustion furnace 25,
After cooling at 6, impurities are removed by a scrubber 27 and exhausted from a chimney 29 by an exhaust gas fan 28. Shaft cooling fan 2
4d is for cooling and holding the rotating shaft.
【０００７】以上から判るように、従来の都市ガスによ

大きく高価である。(2) When activated carbon is heated by burning city gas, harmful gas (eg, nitrogen oxide gas such as NOX) is also discharged, so that the equipment for environmentally friendly gas treatment is large and expensive.
【０００９】（３）、従来の多段炉のように回転しなが
らかき落して、被活性炭を加熱しながら下段で蒸気賦活
させているので、被活性炭が高熱でかきまわされ破損
し、活性炭量は約１割程度減量するから、再生歩留まり
が悪かった。(3) Since the activated carbon is heated and steam activated in the lower stage while rotating and scraping off like a conventional multistage furnace, the activated carbon is stirred by high heat and broken, and the amount of activated carbon is reduced. Was reduced by about 10%, so the regeneration yield was poor.

For example, the Japan Water Works Association (issued in March 1988) “Advanced Water Supply Technical Data (Activated Carbon Treatment Facility)” describes in detail the regeneration heating method, and the heating source is fuel such as city gas or electricity. Furnace heating is employed.

備は小さくなるが、加熱効率が悪い欠点があった。When city gas is used as a heating source,
As described above, a rotating mechanism is required to homogenize the activated carbon to externally heat it, and a secondary combustor is provided outside, the impurities are separated by a scrubber, and the smoke is exhausted. It is large. In the electric furnace method, an electrode is provided between activated carbons, and electricity is supplied. The activated carbon is heated by Joule heat generated by the resistance of the activated carbon, and the incidental facilities are reduced, but there is a disadvantage that the heating efficiency is poor.

摩耗して粉末化するので、再生歩留まりが悪い。[0012] The conventional external heating and regeneration equipment using city gas has a large equipment area, and particularly large auxiliary equipment for exhaust gas treatment. In addition, since the heating process structure for mechanically scraping the activated carbon is used, the granular (approximately φ1 mm) activated carbon is abraded and powdered, resulting in poor regeneration yield.

There has been proposed a method of irradiating the activated carbon with microwaves to raise the temperature by the heat generated by the molecular vibration of the particles of the activated carbon, thereby carbonizing the contamination of the activated carbon and using the activated carbon as regenerated activated carbon.

対象物の固有の誘電体損（ｔａｎδ）が大きい程熱エネ
ルギー変換量が多い。As a familiar microwave source, a home microwave oven is widely used, and a 2.45 GHz tube is used. In our experiment, microwave heating at 2.45 GHz and 500 W is possible, but since activated carbon is a good conductor of electricity, an arc discharge occurs due to the degree of contact between particles, so that a dispersed arrangement is necessary. The principle of microwave heating is to convert millimeter wave radio wave energy to heat energy,
The larger the intrinsic dielectric loss (tan δ) of the object, the greater the amount of thermal energy conversion.
【００２７】活性炭はｔａｎδ≒０．１前後であったの

The temperature could be uniformly raised to 950 ° C. in minutes. Therefore,
It was found that if the target activated carbon was placed in a portion where the electric field in the reactor was uniform, the reactor was heated uniformly.

In order to uniformly heat the activated carbon of
It was 0 mm. This means that D> 20 in the reactor
When the activated carbon depth was set to 0 mm, it was found that heating was not performed uniformly, and it was found that the activated carbon had a limited mounting arrangement size in the case.

The portion immediately below (the left side of XX ′) has a high electric field strength,
As the position moves to the right, a uniform electric field intensity distribution is obtained. Therefore,
By providing the activated carbon 6 in a region where the electric field intensity is uniform, the heating and regeneration temperature control becomes easy, the regeneration heating condition of the activated carbon becomes uniform, and the regeneration quality is stabilized (the temperature of the activated carbon 6 is measured by a thermometer. 9).

At 00 ° C., water evaporation proceeds. When water evaporation stops,
Although the temperature rises rapidly, since the microwave output is controlled by a control unit described later so that T1 = 500 ° C.,

It will be 0 ° C. When the constant temperature control starts, the activated carbon deposits are exhausted as oxidizing gas, but the inside of the pores inside the activated carbon particles is hardly exhausted. That is, by increasing the microwave output, T
By setting 2 = 850 ° C., in the process C, the inner-hole deposits are further desorbed by carbonization, polycondensed, and carbonized and evaporated.

At the time, carbonized deposits on the surface and inner pores of the activated carbon 6 are desorbed and discharged as H 2 O and CO 2 gas, and steam cleaning desorption is performed, so that high quality regenerated activated carbon can be produced. it can. That is, the activated carbon 6 is cooled by the microwave power of zero and the high-temperature water spouted from the pore water pipe 6-2, so that the high-temperature water easily penetrates into the inner hole. Therefore, the vaporized water is immediately injected, and the vaporized water is ejected at the vapor pressure, and the carbonized deposits in the inner hole are discharged to the outside together, so that it is possible to produce high-quality regenerated activated carbon in which the inner hole is cleaned. Water may be sprayed on the activated carbon 6, but the activated carbon 6 is cooled by high-temperature water from below with a microwave output of zero, and the temperature decreases. However, since the high-temperature water easily evaporates immediately in the inner hole, water is used. Higher temperature water has a longer activation time without any extra drop,
It is suitable for cleaning and desorption.

In addition, the utilization water tank 7 is disposed outside the reactor 5 so that measures against microwaves are not required, and ordinary materials such as iron plates can be used instead of expensive materials such as heat insulating materials such as ceramic materials. Not only is it economical, but also the production of the utilized water tank 7 is easy. Further, since the exhaust gas is cooled in the utilization water tank 7, a device having a small capacity can be used as the ozone-side heat exchanger 11A. The exhaust gas from the ozone-side heat exchanger 11A is mixed with a mixer 11B in order to eliminate odors with ozone (OZN) and exhausted to the outside so as not to cause pollution.

にあげる構造として冷却しても良い。The pore water pipe 6-2 is a material that reflects microwaves, and may be, for example, a SUS material. The storage case 6-1 is arranged to be inclined (inclination angle θ). For the inclination, a table on which the storage case 6-1 is tilted is provided, or a support rod that can move the storage case 6-1 up and down is provided in the reactor 5. All use stainless steel. When the activated carbon 6 is in a wet state due to the inclination angle θ, the activated carbon 6 is naturally drained and discharged, but the hinge 6-5 and the opening / closing lid 6-3 are used.
Since water leaks from the gap between the two, water does not accumulate in the storage case 6-1. Therefore, there is no excess hot water during heating, and the temperature can be raised quickly. The present invention can reduce the cost of electricity consumption compared to the case without draining. The upper lid 6-4a has heat insulation properties, and provides an area for exhaust gas in a space with the activated carbon 6. Note that the cooling may be performed by cooling the upper lid 6-4a so that the upper lid 6-4a is raised.
